Program Takes All Cpu?
May 10, 2010
A couple days, I figured up a working program and it was def. faster than what we needed. Now, adding a couple more loops, the program barely uses any memory, but the cpu used spikes up to 90+ and just letting it sit doesn't help.I tried taking out the couple loops I put in, but it does not revert back to being fast. It's nothing big, but since dealing with 1000+ excel files a day, I'd rather not do that by hand.
how many infinite loops vb.net can support without dragging down the system? I know, infinite loops are poor design, but it works.

I am working on a program that takes data from a survey in the program and needs to compile it into a PDF file. Optimally it would just be a snapshot of the filled out survey. I tried using the PrintForm component in the PowerPacks section, but I need a PDF not an EPS.

I am writing a program that takes a SSN into a number field.Issue is when a SSN is entered with a leading 0. Ex. 012-34-5678 The zero is cut off and turns it into an 8 byte field, which is not good for SSN obviously.What can I do to prevent this from happening?

I am not recieving any errors, but the program is not doing what I had expected. I wish to make a program that randomly takes characters (well, not completely randomly. I used the table of letter frequency from wikipedia and included that data in my program by figuring out the max for the random numbers from the percentages in the wikipedia chart.) and adds them to a long list of characters ands saves the file every 5 minutes. I have calculated the timer interval so that the number of miliseconds shown is equal to 5 minutes. I am getting the textwindow, and it is showing (rather rapidly, as I need it to be) a long random list of characters (including spaces). The problems are (A) I am having difficulty saving the text as a file. You'll find the code that is supposed to do that at the bottom. The other problem I am having is once so many characters are added, the ones at the top start disappearing. I would scroll to the top, and each time I did so the letters at the top had changed (this is all during the same test), but I need all characters to be stored when the file saves. Granted, I haven't actually seen one of the saved files as I have not figured out how to make that work. One other thing, not sure if it's important, I haven't run a published version yet. I've only been running the debug builds. Does that affect how it handles actions with files?

I've been working on a program that takes input from a textbox, removes the punctuation, puts the words into an array (using the split method), and compares the array against a reversed copy of itself to determine if it is a word palindrome or not. I understand the logic, but I'm getting kind of caught up as far as what code to us. This is what I have so far, but no matter what I enter into the text box, nothing happens. I'm completely lost as to what I'm doing wrong.

I'm writing a program which takes one item from each of two lists and combines the items in one of three ways selected by the user. The results of the process are provided in either a summary form or a detailed form, again selected by the user. As it's currently developing, this program will contain six subroutines covering each of the six combinations of user selections, which are stored in three Booleans. Selection of the appropriate subroutine is done through traditional "if then else" coding.If I understand OO and Visual Basic (Express 2008) correctly, I could make the subroutines into different variations of one method, which when invoked would automagically use the correct coding depending upon the settings of the Booleans / properties. Assuming this is correct, the problem is that I have no idea how to actually set up code like this.

I'm trying to make a program that takes my old records from Access and moves them to MySQL. Its supposed to take records from 3 different tables in Access to 3 different tables in MySQL. The first table is "Orders" and it sorts the ones to pull to the dataset, taxDS, by "Where Status = 'Waiting Payment' OR 'Cancelled'". Then the second table pulls its info(this is where i'm having trouble) by the "Control_Number" in the "Orders" table, so basically if the control number isnt already in the dataset its not going to pull the data into the new table "FNF Taxes".

I've recently started programming for Visual Basic Express - 2008, and I'm currently trying to make a program which takes a bunch of inputs (Name, Age, x2 score results) and then turns this into an output at the end which varies depending on the score results.
I've stumbled upon a small hinderance, which is that the very final stage which has a Console.Writeline does not appear after testing the program. So, everything else functions fine, but as soon as it gets past the "Console.WriteLine("All pupils have been calculated, the results are...")" command the program closes itself.I'm not looking for much help, just wondering exactly what is causing this to happen. I also realise that my coding is sub-par and is coded in a slightly odd fashion, but I'd rather just get this one to work and use the mistakes from this one to correct my future work.

Im trying to create a program that takes an amount entered by the user and then convert it into Half Dollars, quarters, dimes, nickles, and pennies when the calculate button is clicked. Each coin has its own function and is shown in separate text boxes... right now i cant get it to work correctly. When i try to get half dollars to work it rounds up and then the rest of the coins say 0. How should i do this?

I'm making a program that takes common applications and installs them silently using batch files. Someone would select the programs they would want to install and my program will write a giant batch file and execute it to install whatever they want. Heres the problem, After the user selects the programs they go into either one or two lists. Non Silent Installer List Or Silent installer list.
Some programs I have simply won't go silently so from there they can choose in what order they want to install these programs. Then there is a combo box that tells weather you want to install non silent programs first or last. From there you hit add to batch file and it would add everything in listbox1 and listbox2 in order. Listbox1 would contain just the text "MalwareBytes" for example. Along with Novell Groupwise and Firefox. How do I get that to add to the Batch List as a code and in order? So the user wants Malware bytes added first to the batch file. How do I add that to my batch list as a completely different code?

I need to write a program in VB 2008 express that takes an user entry from a textbox and strips out all the spaces, changes it to either all upper case or all lower case then checks to see if it is a palindrome. I must also include a loop structure and a decision structure. I have seen bits and pieces of code but I do not really know how to put them together. Basically I need it from the button click to the end. ?

Ok, this might be something stupid that im not doing right, but here is my problem. Im moving from my 1st form, a small window, into my second form, that is full screen, but it takes like 4-5 seconds to load the full form. It sucks because during this 4-5 second load time, parts of the form at transparent and it just look bad. I think it might be because i have around 35 labels and a few other objects on the form. Does anyone know a way to make this not happen? Im in VB08.

This operation takes around 7 seconds. I inserted Breakpoints and used F11 to determine that upon MySqlAdapter.Fill is where the lag starts. Both my computer and the server hosting the MySQL database are NOT challenged spec wise. I'm guessing it's the query itself. collectionitem holds the 2 foreign keys linking an itemproperty to a collection. we feed the sproc sId(PK of collection) so that the subquery returns all the itemids from a specific collection and then we use the itemid(PK) in itemproperty. Is there any way to speed up the process?
UPDATE My issue was entirely due to improper indexing. Once I learned which columns to index, everything is extremely smooth!

Ok, this is going to be a bit bizarre, but I'm looking for something strange, so all suggestions are welcome:I have a function that takes a single byte as an argument. From that byte, without using any random function, I need to create two other random bytes. I specifically cannot use the Random object, but fortunately, the other bytes do not need to be random relative to the argument. Also, the argument is random.
Therefore, one other byte can be created by XORing with &HFF, which will create the inverse of the argument. Since the argument is random, the inverse is also random. I need one other technique that will create that last pseudo-random byte. I thought about bit shifting, but that results in something quite a bit less than random (it will be biased high or low, depending on the bit shifting).
One possibility that I am trying is to use CByte(100000/arg). Does anybody have any other suggestions?
EDIT: The result of that equation for all values of the argument is a very interesting pattern. It will probably be fine, but I'd still take suggestions.
